Orthodromic

Orthodromic
This article is about a type of neuronal impulse. For orthodromic distance, see great-circle distance.

An orthodromic impulse runs along an axon in its normal direction, away from the soma.

In the heart, orthodromic may also refer to an impulse going in the correct direction from the atria to the ventricles, in contrast to some impulses in re-entry.
